1.9 M Q 26 l: 24" J 7 W P159113) 480 ,[U TE- STATES" PATENT F I E-T i OI BRQOKIQYN? sew To allwhom it may concern: c

Be it known that I, Josnrn AMonno, a citizen of the i United States, residing at Brooklyn, in the county ofKings, State of New York, have invented certain new and useful Improvements in Sash-Operated Circuit-Closers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention vrelates to new and useful improvements in alarms and particularly to i I through portions of the sashes of a window taken in connection with the accompanying drawing. In the drawing:

Figure 1 is a verticalsectional view showing the invention in elevation in proper position.

Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1 to show the device in side elevation.

Referring particularly to the accompanying drawing, 10 represents the vertical side rail of the upper sash of the window and 11 the horizontal lower rail thereof. This lower rail is cut awayor rabbeted out at 12 to receive the parting stop bead 13, as is usual. In the inner face of this side stile, adjacent the rail 11, there is formed a longitudinal concave recess '14, the purpose of which will presently appear. I p v The upper horizontal rail 15 of the lower sash is represented as secured to the upper end of the vertical side stile 16 of said sash, this rail 15 being rabbeted at 17 for the same purpose as that of the lower rail of the upper sash.

A portion of the parting bead 13 is cut out, as shown at 18, at a point just above the point of contact of the rails 11 and 15, and disposed within the space formed bysAsK-ormzrnncmeurncnosm. i

j Patented June 1921. 19619" i d -f h-ii r i d- 1 i i the reinovalof'the portion of the bead 13,

is a vertically extending elongated block of wood or other insulating material 19. This block is secured to the side stile 20 of the window frame by means of the screws 21, as shown. Disposed transversely through the center of the block, at right angles to the screws 21, is a metal bolt 22, a nut 23 being engaged on the threaded end of the bolt to retain the same within the block. Engaged around the otherend of the bolt, inwardly of the head thereof is a wire 24 which leads to one side of abattery, not shown. Disposed through the lower portion of the block, in parallel relation to the'bolt 22, is

a second bolt 25, each end of which is disposed through one end of a leaf spring 26 which extends vertically at the opposite sides of the block. One of these springs, distinguished from the other by the character 26', is bowed at 27 and normally engaged in the beforementioned recess 14, when the upper sash is in closed position. The intermediate portion of the spring is arranged to contact with the adjacent end of the bolt 22, when the bowed portion of the spring is engaged by the wall of the recess, in the act of lowering the sash, whereby the circuit will be closed and the signal sounded to notify the owner that an attempt is being made'to enter the house. To the outer end of the bolt 25 there is secured a wire 28 which forms part of the circuit for ringing the bell.

Secured on the other face of the block is the before-mentioned spring 26, the same being bowed similarly to that of the spring 26, said bowed portion being adapted to be engaged by one wall of the rabbet' of the vertical rail of the lower sash, when an attempt is made to raise said sash. This engagement of the spring 26, by the rail 15 will move the spring 26 into contact with the adjacent end of the bolt 22 and close the circuit. 7

There is thus provided a novel and improved device whereby a signal will be sounded when either of the sashes of a window is moved from its closed position, thus notifying the owner of an attempt at burglary.

What is claimed is: I

A circuit closer for a window alarm comprising an insulated block having a central enlarged portion and enlarged end portions resulting in intermediate narrow neck por- 'tions, a metal terminal contact member distact therewith, and with their free ends di- 10 cured to the opposite ends of the, last-named posed through the central enlarged portion rected inwardly" toward the other neck porof the block, a metal terminal member distion.
